4 Recall What holds ionic compounds together?

Chemistry
1 answer:
Kazeer [188]3 years ago
7 0

Answer:

The opposite charges of the atoms hold the atoms together. One atom can have a positive charge while the other can have a negative charge and this causes an electrostatic attraction causing the atoms to stick to each other like glue. For example, two magnets, can only be attracted to each other when one side of the magnet has a "-" while the other magnet on one side has a "+". They are attracted to each other by these varying charges. The same applies to ionic compounds which are held together by the varying charges of the ions.

the atomic mass of chlorine is 35.45 u. Is it possible for any single atom of chlorine to have a mass number of exactly 35.45? E
KonstantinChe [14]
No, this number is the result of the natural mixture of Cl-35 and Cl-37, which produces the observed <span>value.

</span><span>The mass of Cl on the periodic table is 35.45 atomic mass units. This is an average mass of the isotopes (different Cl atoms in nature). Most Cl atoms in nature have a relative mass of about 35 atomic mass units. Most of the remaining Cl isotopes have a relative mass of 37 atomic mass units. </span>

An analysis of a sugar compound is found to contain 132 grams of carbon (C), 22 grams of hydrogen (H), and 176 grams of oxygen (
ddd [48]
132 g of C  ,   22 g of H   , 176 g of O

132 + 22 + 176 => 330 g <span>of the substance

</span>Now convert the masses in <span>moles :
</span>
C = 12.0 u        H = 1.0 u       O = 16.0 u

C = 132 / 12.0 => 11 moles

H = 22 / 1.0 => 22 moles

O = 176 / 16.0 => 11 moles

Using the values obtained the lowest proportion in mols of elements present, simply divide the values found for the least of them<span>:
</span>
C = 11 / 11 => 1

H = 22 / 11 => 2

O = 11 / 11 => 1

 formula empirically <span>is : CH</span>₂O

hope this helps!
